Butterball valve from Milwaukee Valve
Milwaukee Valve’s Slow-Close Butterball Valve will prevent water hammer damage in a fire sprinkler system by carefully controlling the valve’s closing, eliminating the shock that may cause pipes to fail. The Butterball valve is available from 1” to 2 ½” with threaded or grooved ends and has UL and FM approvals for 175 psi. The New York City Board of Standards and Appeals approves the valve for 350 and 500 psi for high-rise applications.
